Replacing the Valve Positioning Drive for the Reject Circuit [00367768] C&P12 Placement Head

Service Manual SIPLACE D4

4.5.9.3 Mechanical Adjustment (From Version 03)

Setting the valve positioning drive for the reject position

NOTE:

The valve positioning drives of the DLM1 and DLM3 head reject position can be set with the

adjustment valve plungers.

ATTENTION:

Even if your placement machine does not use the valve positioning drive for rejecting

components (rejection vertically down), the position of this drive must still be correct. If this is

not the case, an incorrectly set valve positioning drive could have a negative influence on the

plunger positions during the reference run and during star rotation.

X Fit the dismantled placement head onto the

head mount and place this down on the front

or place the placement head down on a soft,

ESD conductible surface on its front.

X The lockscrew (at the bottom side of the

placement head) and the fastening screw of

the valve positioning drive need to be

loosened or are only screwed in slightly during

assembly of the drive.

X Fit the adjustment valve plunger (1) in place of

the valve plunger, for the reject position (R) -

as shown in the diagram.

X Turn the adjustment valve plunger so that the

tips of the two centering pins are near to the

cam disk behind the ball bearing.

X Use a pointed object to carefully turn the cam

disk so that it is in the "starting position" (ball

bearing horizontally aligned next to the drive

shaft).

X Carefully turn the placement star in the

direction of the valve positioning drive so that

the two centering pins behind the ball bearing

grasp the fixtures on the cam disk. The

adjustment valve plunger (1) swivels into the

correct position (centering pins parallel to cam

disk).

NOTE:

As the cam disk of the reject valve

positioning drive is behind the

connection board, this setting is slightly

more complex than that for the

placement circuit.

X Press the valve positioning drive in the

direction of the placement star and fasten the

drive holder with a 2.5 mm Allen key.

X Now tighten the locking threaded pin with an

Allen key of size 0.89 mm. Press the valve

positioning drive against it. Do not tighten

excessively as this could push the valve

positioning drive "backwards".

X Remove the adjustment plunger by turning the

placement star back and then rotating the

adjustment plunger out of the valve housing.

X Then replace the adjustment plunger with a

plunger and protection ring.
